Abstract

The buying and selling transaction system that many people use today is the online buying and selling system. In this system, there is a process of goods delivery by one branch of a freight forwarder in Indonesia, namely SiCepat Express Baleendah. In the process of shipping goods, a delivery route with the shortest path is needed in order to minimize of the goods delivery process. The problem of the route of goods delivery can be solved by one of the algorithms in the Traveling Salesman Problem (TSP), namely the Cheapest Insertion Heuristic (CIH) Algorithm. This study aims to determine the shortest route and distance for goods delivery using the CIH Algorithm by the Asymmetric TSP CIH application, as well as knowing its efficiency compared to the route that used by SiCepat Express Baleendah. The result shows that the use of the CIH Algorithm is proven to produce a more efficient delivery route than the route created by SiCepat Express Baleendah. Based on the goods delivery route from SiCepat Express Baleendah, the result of the total distance is 18.55 km. On the other hand, based on the CIH Algorithm, the delivery route obtained result is 13.45 km. The efficiency of using the CIH Algorithm is 27.48% better than the result from SiCepat Express Baleendah route.

Abstract

This research aims to improve student learning outcomes in Islamic religious education learning by using problem-based learning. This research is a classroom action research that uses four steps, namely planning, action, observation and reflection. The subject of this research is elementary school students. The data of this study was obtained by test and observation techniques. Tests are used to measure learning outcomes and observations are used to analyze the learning activities of teachers and students. The data analysis technique used in this study is descriptive statistics by comparing the results obtained with research success indicators. The results of the study show that problem-based learning can improve student learning outcomes in Islamic religious education learning. This can be seen from the increase in the percentage of student learning completeness in each cycle with details of 40.19% in the pre-cycle, 65.37% in the first cycle and 89.72% in the second cycle. Thus, the use of problem-based learning can be used as an alternative to improve student learning outcomes in Islamic religious education learning.

Abstract

This study aims to determine whether the Community Units (RW) are independently able to handle waste without assistance from the Regional Government. Waste management in Bandung Regency is becoming increasingly complex with the increasingly full capacity of the Sarimukti Final Waste Disposal Site (TPA), West Bandung Regency. This has caused the Regional Government together with the West Java Provincial Government to take strategic steps to reduce the volume of waste sent to the TPA. One of the main strategies that is being actively carried out is to encourage the community to start sorting waste from the source, especially at the household level. In addition, the Bandung Regency Government has also introduced the "Zero Food Waste" program. Data were obtained through surveys, interviews, and direct observations in RW 12, Cimenyan District. The conclusion of this study is that the Community Units (RW) have not been able to manage waste independently without assistance from the Regional Government. The results of the study are expected to help the Regional Government (Pemda) design a more effective waste management strategy

Abstract

Pajak adalah pembayaran wajib kepada pemerintah yang dilakukan oleh individu, perusahaan, atau entitas hukum lainnya. Tujuan utama pajak adalah untuk mendanai biaya pemerintah untuk program dan layanan publik seperti pendidikan, kesehatan, infrastruktur, pertahanan, dan banyak lagi. Daerah harus memiliki sumber daya penerimaan daerah yang cukup jika mereka ingin melaksanakan pembangunan daerah dan meningkatkan pelayanan kepada masyarakat. Pendapatan Asli Daerah (PAD) adalah salah satu sumber penerimaan daerah untuk membiayai berbagai program pajak daerah seperti pembangunan dan pelayanan publik di tingkat lokal, seperti pendidikan, kesehatan, dan infrastruktur, pemerintah harus memastikan bahwa pendapatan ini digunakan dengan benar untuk meningkatkan kesejahteraan masyarakat lokal. Pajak hotel dan pajak restoran merupakan dua jenis pajak daerah yang potensinya semakin berkembang seiring dengan semakin diperhatikannya adanya komponen pendukung yaitu sektor jasa, pembangunan maupun pariwisata dalam kebijakan peningkatan pembangunan daerah. Dari analisis yang dilakukan, efektivitas pajak hotel dan restoran pada tahun 2020 sampai tahun 2022 terbilang kurang efektif dengan rasio kurang dari 50% sedangkan untuk kontribusinya terhadap Pendapatan Asli Daerah masih terbilang sangat kurang dengan rasio kurang dari 10%.

Abstract

Pencapaian pembangunan nasional dapat diraih dari potensi sumber daya manusia yang berkualitas, karena potensi sumber daya manusia ini merupakan modal dasar pembangunan. Dilihat dari transaksi di Indonesia yang semakin luas dan berkembang, perlu adanya pengikat yang sah dari transaksi bisnis tersebut. Perusahaan XYZ merupakan perusahaan yang bergerak di bidang penjualan. Sebagai usaha untuk meningkatkan bisnis tersebut, maka perusahaan perlu mengatur jumlah persediaan produk agar tidak mengalami kekosongan stok dan agar perusahaan tidak mengalami kerugian. Dilihat dari data penjualan produk X pada tahun 2016 sampai dengan tahun 2019, penjualan produk X setiap tahunnya selalu mengalami kenaikan. Maka untuk mengetahui jumlah penjualan pada periode-periode berikutnya akan digunakan metode Double Exponential Smoothing untuk meramalkan jumlah penjualan tersebut. Hasil akhir yang diperoleh yaitu peramalan berupa nilai jumlah penjualan produk X pada perusahaan XYZ pada periode-periode berikutnya, dimana semakin banyak periode yang diramalkan maka akan semakin tinggi pula hasil peramalan jumlah produk X yang terjual.   Forecasting Analysis of Product X Sales at Company XYZ Using Double Exponential Smoothing Method Achievement of national development can be achieved from the potential of quality human resources, because the potential of these human resources is the basic capital of development. Judging from the transaction in Indonesia, which is getting wider and growing, it is necessary to have a legal binding of the business transaction. XYZ Company is a company engaged in sales. In an effort to improve the business, the company needs to regulate the amount of product inventory so that it does not experience a stock vacancy and so that the company does not experience losses. Judging from the sales data for product X from 2016 to 2019, sales of product X always increase every year. So to find out the number of sales in the following periods, the Double Exponential Smoothing method will be used to predict the number of sales. The final result obtained is forecasting in the form of the value of the number of sales of product X at company XYZ in the following periods, where the more periods are forecasted, the higher the forecasting results for the number of products X sold.
